Parameters For The Sse Function; Parameters For The Pous Function - ABB +Q950 User Manual

Index Name
STO.14 Time to zero speed
with STO and modoff

Parameters for the SSE function

These parameters are related to the Safe stop emergency (SSE) function of the FSO module.
The FSO module can activate the SSE function in internal fault situations.
Index Name
SSE.13 SSE function

Parameters for the POUS function

These parameters are related to the POUS function in all FSO modules in the network.
Index Name
POUS.01 POUS activity and
version
Example value Description
2000 ms Sets the time after which the acknowledge-
ment is allowed after coast stop in the STO,
SS1 and SSE functions.
This parameter is relevant only when the
FSO module activates the STO or SSE
function in internal fault situations. Set this
value always at the start-up. Use the estim-
ated time in which the motor coasts to a
stop from the maximum speed.
Note: The default value after factory reset
is 3,600,000 ms. Always check this paramet-
er after factory reset.
Example value Description
Immediate STO or Sets the type of the SSE function.
Emergency ramp
Immediate STO: The FSO module activates
the inverter unit STO function immediately
after the SSE request.
Emergency ramp: The FSO module first
ramps down the motor speed and when the
speed is below the zero speed limit, it activ-
ates the STO function. SAR0 parameters
define the deceleration ramp (for more in-
formation, see the FSO module user's
manual).
For the +Q950 option, ABB has set this
parameter to value Immediate STO at the
factory. Adjust the default value when ne-
cessary.
Note: The default value after factory reset
is Emergency ramp. Always check this
parameter after factory reset.
Example value Description
Version 1 Activates or deactivates the POUS function
and shows the version of the POUS func-
tion.
Version 1: Activates the POUS function.
